Title: Next Generation Grid: Integrating Parallel and Distributed Computing Runtimes from Cloud to Edge Applications

Abstract: We look again at Big Data Programming environments such as Hadoop, Spark, Flink, Heron, Pregel; HPC concepts such as MPI and Asynchronous Many-Task runtimes and Cloud/Grid/Edge ideas such as event-driven computing, serverless computing, workflow and Services. These cross many research communities including distributed systems, databases, cyberphysical systems and parallel computing which sometimes have inconsistent worldviews. There are many common capabilities across these systems which are often implemented differently in each packaged environment. For example, communication can be bulk synchronous processing or data flow; scheduling can be dynamic or static; state and fault-tolerance can have different models; execution and data can be streaming or batch, distributed or local. We suggest that one can usefully build a toolkit (called Twister2 by us) that supports these different choices and allows fruitful customization for each application area. We illustrate the design of Twister2 by several point studies.

Keynote Speaker 2: Prof. Jie Wu, Temple University, USA (IEEE Fellow)
Title: Joint Scheduling of Overlapping Phases in the MapReduce Framework

Abstract: MapReduce includes three phases: map, shuffle, and reduce. Since the map phase is CPU-intensive and the shuffle phase is I/O-intensive, both can be conducted in parallel. This talk focuses on joint scheduling optimization of overlapping map and shuffle phases to minimize average job completion time. Challenges arise due to the dependency relationship between the map and shuffle phases since the shuffle phase relies on data emitted by the map phase. Our key observation is that the optimal schedule is trackable in two special cases. The first case is where the job set is pairable, i.e., the jobs are paired to avoid under-utilization of the I/O. The optimal schedule executes pairs of jobs depending on their size from smallest to largest. The second special case is where the job set is unilateral dominant, [KNW1] i.e., all jobs are simultaneously map-heavy, balanced, or shuffle-heavy. The optimal schedule executes the unilaterally dependent jobs in size order from smallest to largest. When the job set is a union of a pairable job set and a unilateral dominant [KNW2] job set, we propose an approximation schedule with a bound of 2 that resembles a mixture of the two optimal schedules above. Consequently, an arbitrary job set can be divided into two subsets to approximate the two special cases. Real data-driven experiments validate the efficiency and effectiveness of our algorithms.

Keynote Speaker 4: Prof. Lajos Hanzo, University of Southampton, UK (Fellow of the Royal Academy of Engineering of UK, Fellow of IEEE)
Title: Quantum-Search Algorithms, Quantum Codes and All That...

Abstract: Since Marconi demonstrated the feasibility of radio transmissions, researchers have endeavored to realize the dream of flawless wireless multimedia telecommunications, creating the impression of tele-presence - at the touch of a dialling key...

However, making this dream a reality required 'quantum' leaps both in digital signal processing and in its nano-electronics based implementation, facilitated by advances in science both in Edinburgh and farther afield. This process has been fueled by a huge consumer market. Moore's laws has indeed prevailed since he outlined his empirical rule-of-thumb in 1965, but based on this the scale of integration is set to depart from classical physics obeying the well-understood rules revealed by science and enter into a new world, where the traveler has to obey the sometimes strange new rules of the quantum-world. The quest for quantum-domain communication solutions was inspired by Feynman's revolutionary idea in 1985: particles such as photons or electrons might be relied upon for encoding, processing and delivering information. During the last three decades researchers and engineers often considered a pair of open problems. Firstly, classic systems relying on the efficient processing capability of quantum-search algorithms were considered in the area of quantum-assisted communications, while the branch of quantum-domain communications relies on quantum channels. The latter may simply be constituted by the deleterious effects of the environment perturbing the quantum-state particles.In wireless communications we often encounter large-scale search problems, some of which may be efficiently solved with the aid of bio-inspired random guided algorithms or quantum-search techniques. For example, Grover's algorithm is capable of searching through an N-element data-base with the aid of √N cost-function evaluations. Commencing with a brief historical perspective, a variety of efficient quantum-assisted solutions will be exemplified.

Keynote Speaker 5: Prof. Jianhua Ma, Hosei University, Japan
Title: From Personal Big Data to Personal Cyber Buddies in Hyperworld

Abstract: Cyberspace has emerged as an unprecedented digital space in addition to conventional spaces, and further brought about a new global digital environment known as cyberworld. We are undergoing the revolutionary process of cyberization to form the novel cyberworld and reform existing physical, social and mental worlds towards a cyber-enabled hyperworld. Can we successfully adapt to these new worlds to truly benefit from these cyber technologies and live better in the complex and unknown cyber and cyber-integrated new world environments? It appears that human abilities in perception, communication, management, control and cognition will not be sufficient to directly handle so many cyber things and cyber-conjugated physical, social and mental things. This talk presents a novel way to create a group of human-centered or individual-oriented cyber buddies that may help an individual’s activities in the cyber-enabled hyperworld. These personal cyber buddies are expressed as a general notation x-I including Cyber-I, Wear-I, Robo-I, Ambi-I, Web-I, Social-I and Health-I. The main features and functions of these personal cyber buddies are explained, and their future perspectives are discussed.

Keynote Speaker 7: Professor Kin K. Leung, Imperial College London, UK (IEEE Fellow)
Title: Service Placement and Migration in Mobile Edge Clouds

Abstract: Mobile edge cloud (MEC) is a new cloud computing paradigm, which makes use of small-sized edge clouds to provide real-time services to users. Due to the coexistence of the core (centralized) cloud, users, and one or multiple layers of MECs, an important problem is to decide on which computational entity to place and execute different components of an application. This application (or workload) placement problem is notoriously hard, and therefore, heuristic algorithms without performance guarantees are generally employed.

In this talk, the speaker will first address the application placement problem. The user application and the physical computing system are modeled as an application graph and a physical graph with resource demands or availabilities annotated on them, respectively. It is shown that the optimal solution or solution with performance bounds can be obtained for specific graph structures.

As the second part of this talk, the speaker will discuss the issues of dynamic service migration in MECs. As users move over time, the MEC components that have been providing service to the users will no longer be able to do so efficiently and service migration to other components is thus required. It is challenging to make these migration decisions in an optimal manner because of the uncertainty in user/MEC mobility as well as possible non-linearity of the migration and transmission costs. The service migration problem can be formulated as the Markov Decision Process (MDP), which captures general cost models and provides a mathematical framework to design the optimal service migration policies. To overcome the computation complexity, the underlying state space is approximated based on the distance between the user and service locations. The effectiveness of the proposed approach is illustrated by simulation using real-world mobility traces of taxis in San Francisco.

Keynote Speaker 9: Prof. Hai Jin, Huazhong University of Science and Technology, China (Cheung Kung Scholars Chair Professor, Fellow of the CCF)
Title: Towards Dataflow-based Graph Accelerator

Abstract: Existing graph processing frameworks greatly improve the performance of memory subsystem, but they are still subject to the underlying modern processor, resulting in the potential inefficiencies for graph processing in the sense of low instruction level parallelism and high branch misprediction. These inefficiencies, in accordance with our comprehensive micro-architectural study, mainly arise out of a wealth of dependencies, serial semantic of instruction streams, and complex conditional instructions in graph processing. In this talk, we propose that a fundamental shift of approach is necessary to break through the inefficiencies of the underlying processor via the dataflow paradigm. It is verified that the idea of applying dataflow approach into graph processing is extremely appealing for the following two reasons. First, as the execution and retirement of instructions only depend on the availability of input data in dataflow model, a high degree of parallelism can be therefore provided to relax the heavy dependency and serial semantic. Second, dataflow is guaranteed to make it possible to reduce the costs of branch misprediction by simultaneously executing all branches of a conditional instruction. Consequently, we make the preliminary attempt to develop the dataflow insight into a specialized graph accelerator. We believe that our work would open a wide range of opportunities to improve the performance of computation and memory access for large-scale graph processing.

Keynote Speaker 10: Prof. Vijay Varadharajan, The University of Newcastle, Australia (FIEE, FBCS, FACS, FIEAust, FIMA)
Title: Security Challenges in Software Defined Networks Policy based Security Architecture for Software Defined Networks

Abstract: As networks expand in size and complexity, they pose greater administrative and management challenges. Increasingly, current networks are highly heterogeneous with many different devices, from small sensors to network routers to many different clients and servers and peripherals. Furthermore, these devices use different network technologies such as fixed, wireless and mobile networks. In such a complex heterogeneous environment, management of network devices, of mobility of users and devices, the dynamic variation in networks (due to failure of devices and network links), as well as the dramatic increase in security attacks are posing serious challenges.

Software Defined Networks (SDN) is rapidly emerging as a disruptive technology, poised to change communication networks much the same way cloud computing is changing the “compute” world. It is altering the texture of modern networking, moving away from the current control protocols dominant in the TCP/IP Internet stack, towards something more flexible and programmable. It is potentially changing the way networking will be conducted in the future, by enabling devices that are open and controllable by external open software, unlike today’s proprietary network equipment that has protocols embedded into them by the vendors.

In this sense, SDN opens up new avenues of research to realize network capabilities that were impossible or cumbersome before, thereby helping to make future networks more manageable and practicable. Although SDN offers several advantages to deal with complexities in current networks, a critical issue in SDN at present is that of security. Securing networks is becoming more challenging to businesses, especially with bring your own devices (BYOD), increased cloud adoption and the Internet of Things (IoT).

In this talk, we will start by looking at the security challenges that arise in Software Defined Networks (SDNs). We will discuss the various security threats in SDNs, and highlight the characteristics that are unique to SDN which make it suitable to counteract these threats and attacks. Then we will propose a policy based security architecture for a distributed SDN environment. We will discuss the specification of security policies in both intra and inter domain environments, and illustrate them with example scenarios. Our architecture can be used in either reactive or in a proactive mode. In the reactive mode, the first packet of the flow received by switch will trigger the insertion of flow entries in switches in the network. In the proactive approach, the flow tables in the switches are pre-configured by the Controller, thereby reducing the flow setup times. Then we will describe the implementation of the SDN security architecture and discuss some results. Finally we will conclude the talk by outlining some further work extending the proposed SDN security architecture with IoT devices.

Title: Tracking Ubiquitous Radio Signal Activities: Sensing and Security Application Perspectives

Abstract: Nowadays, wireless signals are ubiquitous and are around of us; some pass through us and some reflect off us. Tracking these signals gives the limit of ISM band radiometric detection to a new level, including motion detection, gesture recognition, localization, and even classification. This research focuses on answers to questions, without interrupting the data communication, how can we leverage wireless radio signals passively for various sensing applications. For example, just raise your hand, finger-swipe the air, your lights will power down; swipe your hand left-to-right or right-to-left, your TV channel will be changed; or just tap your mobile screen to see your heartbeat? All of these, we can achieve with our wireless devices (namely, Wi-Fi, wireless sensor), but without the need of any sensing or additional transmitting unit. We will highlight these signals can extend our senses, enabling us to see moving objects through walls, behind the closed door, and in the dark where even cameras don’t work well and security personnel cannot get in. We will discuss a set of emerging wireless sensing applications that can change our current thoughts on sensing and see how such signals activities can be utilized to penetrate our security. Finally, we cover some basic methods, techniques, challenges how signals are used in such applications.
